Hi Kylieu,
Thanks for posting your concern in the forum.
I'm sorry to hear about your difficulties with the information in the ABA file you've generated. In my understanding, the ABA file information is taken from the information from the Employee card's Payment details. I suggest checking the employee card to make sure there is information for the ABA file. If the information is complete in this window but the ABA file is still blank, feel free to let us know and we'll check this further.
Let us know if you require any further assistance.
Thanks,
Genreve
